Description

Technical Field

[0001] This utility model relates to the field of repair pliers technology, and in particular to a mechanical repair pliers. Background Technology

[0002] In the machinery manufacturing industry, mechanical repair pliers occupy an important position and are indispensable key tools. Skilled workers utilize various fitter's tools, measuring instruments, and auxiliary equipment to perform their work, primarily covering the maintenance, repair, assembly, and debugging of all kinds of mechanical equipment. These skilled workers, with their superb manual skills and professional knowledge of mechanical principles, accurately diagnose and repair faults in mechanical equipment. Simultaneously, they undertake the daily maintenance responsibilities of the equipment, thereby ensuring its stable, efficient, and continuous operation.

[0003] Among them, mechanical repair pliers, as a commonly used tool, have obvious drawbacks in their traditional structure. Currently, most mechanical repair pliers use a one-piece construction, where the pliers bar and head are molded as a single unit. In practical applications, especially in confined spaces, the inability to flexibly adjust the bar's tilt angle makes it difficult to operate the pliers smoothly. This limitation significantly restricts the effective application of mechanical repair pliers in special working conditions, negatively impacting the efficiency and quality of repair work. Therefore, a new type of mechanical repair pliers is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanical repair pliers. Through a disc and several limiting holes on its circumference, the pliers lever can rotate on the disc. After rotating to a suitable position, it is positioned by a locking rod, thus achieving the purpose of adjusting the tilt angle of the pliers lever. It can be used in smaller spaces and is easy to store, overcoming the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mechanical repair pliers includes a plier head, with two connecting blocks fixed to both sides of the tail of the plier head. One end of each of the two connecting blocks is connected to a disc, and a plier bar is rotatably connected to each of the two discs. Limiting holes are provided at equal intervals on the curved surface of the discs, and a snap-fit ​​component that cooperates with the limiting holes is installed in the plier bar.

[0007] As a further improvement of this utility model: the connecting block is provided with a horizontal section and an inclined section, and the disc is fixed at the end of the inclined section.

[0008] As a further embodiment of this utility model: one end of the clamp rod is provided with a connecting groove, the disc is located in the connecting groove, and the disc and the clamp rod are rotatably connected by a connecting pin.

[0009] As a further embodiment of this utility model: the snap-fit ​​component includes a movable slot formed on the clamp bar and close to the connecting slot, a guide hole is provided on the clamp bar and located between the movable slot and the connecting slot, and a spring hole is provided at the end of the movable slot away from the connecting slot.

[0010] As a further embodiment of this utility model: the snap-fit ​​component also includes a locking rod inserted into the guide hole, one end of the locking rod forming a plug-in fit with the limiting insertion hole, and the other end of the locking rod is connected to a screw rod, on which a push-pull rod is screwed.

[0011] As a further embodiment of this utility model: a spring is installed in the spring hole, one end of the spring extends into the movable slot, the screw is inserted into the inside of the spring, the push-pull rod is slidably engaged in the movable slot, and both ends of the push-pull rod extend to the outside of the movable slot.

[0012] As a further improvement of this utility model, a toggle block is provided at one end of the locking rod near the limiting insertion hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The pliers can rotate on the disc by means of a disc and several limiting holes on the circumference of the disc. After rotating to the appropriate position, the locking rod can be used to fix the position, thereby achieving the purpose of adjusting the tilt angle of the pliers. It can be used in small spaces and is easy to store.

[0015] 2. By setting an inclined section on the connecting block, the disc is located on the side diagonally below the pliers head. At this time, when the pliers are stored, the pliers can rotate on the disc to a position horizontal with the pliers head. At this time, the pliers and the pliers head are folded, which takes up little space and is easy to store. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A mechanical repair pliers includes a plier head 1, with two connecting blocks 2 fixed on both sides of the tail of the plier head 1. One end of each connecting block 2 is connected to a disc 3, and plier bars 4 are rotatably connected to each of the two discs 3. Limiting holes 15 are provided at equal intervals on the curved surface of the discs 3, and a snap-fit ​​component that cooperates with the limiting holes 15 is installed in the plier bars 4.

[0023] The connecting block 2 is provided with a horizontal section and an inclined section, and the disc 3 is fixed at the end of the inclined section.

[0024] One end of the clamp bar 4 is provided with a connecting slot 5, the disc 3 is located in the connecting slot 5, and the disc 3 and the clamp bar 4 are rotatably connected by a connecting pin 8.

[0025] The snap-fit ​​component includes a movable slot 6 on the clamp bar 4 and near the connecting slot 5. A guide hole 14 is provided on the clamp bar 4 at the part between the movable slot 6 and the connecting slot 5. A spring hole 11 is provided at the end of the movable slot 6 away from the connecting slot 5.

[0026] The snap-fit ​​component also includes a locking rod 12 inserted into the guide hole 14. One end of the locking rod 12 is engaged with the limiting insertion hole 15, and the other end of the locking rod 12 is connected to a screw rod 9. A push-pull rod 7 is screwed onto the screw rod 9.

[0027] A spring 10 is installed in the spring hole 11. One end of the spring 10 extends into the movable slot 6. The screw 9 is inserted into the inside of the spring 10. The push-pull rod 7 is slidably engaged in the movable slot 6, and both ends of the push-pull rod 7 extend to the outside of the movable slot 6.

[0028] By moving the push-pull rod 7 away from the clamp head 1, the locking rod 12 is disengaged from the limiting socket 15, and the spring 10 is compressed. Then, the clamp rod 4 can be rotated around the disc 3 to achieve flexible adjustment of the angle of the clamp rod 4. When the push-pull rod 7 is released, it returns to its original position under the rebound action of the spring 10, and the end of the locking rod 12 is inserted into the limiting socket 15, locking the clamp rod 4 again.

[0029] The inclined section on the connecting block 2 allows the clamp bar 4 and the clamp head 1 to be folded, thereby reducing the space occupied and making it easier to store.

[0030] Example 2 is an optimization based on Example 1. Specifically, a toggle block 13 is provided on one end of the locking rod 12 near the limiting insertion hole 15.

[0031] The locking rod 12 can be rotated by the toggle block 13, which can drive the screw 9 to be screwed into the middle of the push-pull rod 7 in the movable slot 6, which facilitates assembly and subsequent disassembly and maintenance.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
